Nahuatl is a language from Mexico, belonging to the Uto-Aztecan group of languages. It was the language of the Aztecs, as well as of the Pipil, an ancient Mexican people that settled in the western area of what is now El Salvador. Nahuatl has made an indelible mark into modern Spanish, especially to the varieties of this language as spoken in Mesoamerica.
Nahuatl is still spoken by more than two and a half million people and used as a cultural vehicle, particularly in Mexico.
Reading from the archives of elcastellano.org/noticias I found a very interesting article about the join publication of a Diccionario del náhuatl en el español de México (Dictionary of Nahuatl terms in Mexican Spanish) by the Government of the Federal District of Mexico and the UNAM (The Autonomic National University of Mexico).
The article at the site referred to here is by Juan Solis from El Universal. It reports that the dictionary incorporates more than 2000 Nahuatl lexical and toponymic terms. It adds that according to the UNAM academic Carlos Montemayor, the coordinator in charge of the dictionary’s publication, the new lexical book also includes Nahuatl names and botanical terms.
This Dictionary of Nahuatl terms in Mexican Spanish is a great achievement towards registering, studying, maintaining and preserving for future generations the linguistic wealth that the ancient Native American tongues such as Nahuatl have given to the Spanish language.
